It was then compared to other wigs Williams has worn on different movies.

The official trailer for Sony Pictures' "Venom" was released Monday night and while we finally got our first look at the film's antihero a lot of fans can't stop talking about one aspect of the trailer: Michelle Williams' wig.

Does this look natural to you? Sony Pictures

Here's Williams in real life. The actress has much shorter hair.

In the movie, Williams plays the girlfriend of journalist Eddie Brock (Tom Hardy) who becomes a host to the alien, Venom.

Fans were quick to call out the questionable wig for looking unnatural.

Many also pointed out this isn't the first time Williams has a wig onscreen that didn't suit her.

Fans pointed to hair pieces from "All the Money in the World" and the actress' most recent film, "I Feel Pretty."

"Venom" is in theaters October 5. You can watch the trailer with Williams' wig below.
